Description

The data set consists of records for European pear rust (Gymnosporangium sabinae) for the UK. Records are gathered by the Royal Horticultural Society from members of the Society.
The RHS and the Sylva Foundation have linked their resources to monitor the distribution and progression of European pear rust in this joint venture. This brings together the experience of the RHS plant pathologists with the online monitoring system setup by the TreeWatch initiative. The collective data increases the distribution of Gymnosporangium sabinae records in the UK.

Purpose

Data have been collected as part of a survey and monitoring study using the TreeWatch initiative and the Royal Horticultural Society Advisory Service. The survey aims to establish the distribution of European pear rust, a major disease of pear trees (Pyrus). The on-line survey will also gather data on the development of the disease during 2011.
Pear rust was once a rarity in the UK with only sporadic sightings. In the last few years, European pear rust has been increasingly observed and it is now one of the main rust diseases occurring in gardens.
